Application filed May 12, 1913. Serial No. 767,176.

To all whom t may concern Be it known that I, NATHAN JOHNSTON, a citizenof the United States, residing at Sugden, in the county of Jefferson andState of Oklahoma, have invented a new and useful Fireplace, ot whichthe following is a specification.

The invention relates to improvements in iireplaces.

The object of the present invention is to improve the construction offireplaces, and to provide a simple, cheap and practical chimney andiireplace of strong and durable construction, adapted to be readilymanufactured and easily and quickly arranged for use, and equipped withan interiorly arranged damper for controlling the passage or flue of thechimney and with a vertically movable blower or screen adapted tocooperate with the damper for controlling the draft and also to bearranged to expose the iire or to close completely the replace either toprotect a room or apartment from the fire during the night and at othertimes, and also during seasons of the year when a tire is not required.

vWith these and other objects in view, the invention consists in theconstruction and novel combination of parts hereinafter fully described,illustrated in the accompanying drawing, and pointed out in the claimshereto appended; it being understood that various changes in the form,proportion, size and minor details of construction, within the scope ofthe claims, may be resorted to without departing from the spirit orsacrificing any of the advantages of the invention.

In the drawing Figure l is a vertical sectional view of a chimney,having a fireplace constructed in accordance with this invention. Fig. 2is a horizontal sectional view on the line 2 2 of Fig. l. Fig. 3 is asimilar view on the line 3-3 of Fig. 1 Fig. 4 is an enlarged detailsectional view on the line @1r-l of Fig. 1. Fig. 5 is a detailperspective view of the hearth plate. Fig. 6 is a detail viewillustrating the arrangement of the set screw for securing the blower inits adjustment.

Like numerals of reference designate corresponding parts in all thefigures of the drawing.

In the accompanying drawing in which is illustrated the preferredembodiment of the invention, the chimney 1, which may be made in anynumber of vertically arranged sections, is illustrated in the drawing asconstructed of sheet metal, but it may be made of various othermaterials, and it comprises in its construction a vertical front wall 2,vertical side walls 3 and a rear wall 4L, preferably formed integral, asclearly illustrated in Figs. 2 and 3 of the drawing. The front wall 2 isprovided at its lower portion with a ireplace opening 5, extendingupwardly from the lower edge of the front wall, and terminating short ofthe side walls and provided at the front corners of the chimney withvertical guides 6 for a vertically adj ustable blower or screen 7. Thevertical guides 6, which are approximately U-shaped in horizontalsection, are shown as formed integral with the side portions of thefront wall by extending the side portions inwardly. The chimney is alsoprovided with extension guides 8 consisting of strips of metal bentlongitudinally to form two sides or flanges and a connecting portion.The extension guides are approximately U-shaped in cross section, andtheir lower portions t around the guides 6 of the front wall and arearranged between the said guides and the adjacent portions of the sidewalls and the front walls, whereby the extension guides 8 are firmlyheld in a vertical position. The extension guides preferably extendupwardly from the lower edges of the chimney a sutlicient distance abovethe ireplace opening to permit the blower or screen 7 to be arrangedsubstantially above the fireplace opening where the greater portion ofit is out of View.

The screen or blower is equipped adjacent to its lower edge with acentrally arranged projecting knob 9, having a shank 10 adapt ed to beengaged by a hook 11, or other suitable catch for retaining the blowerin an elevated position. When the blower or screen is raised, asillustrated in Fig. l of the drawing, it provides a double thickness atthe front of the chimney above the tireplace to prevent a mantle orother woodwork from becoming excessively heated. Also any suitable meanssuch as a set screw 7a may be provided for securing the screen at anintermediate adjustment between the bottom of the chimney and the top ofthe iireplace to arrange the blower or screen for controlling the draftto cause a fire to burn with the desired rapidity.

The chimney is equipped with interiorly arranged vertical side plates12, constructed ot' heavy sheet metal or other suitable material andextending from the corner guides to the rear wall of the chimney andprovided at their liront and rear edges with vertical flanges 13.arranged at right angles to the planes or the side plates 12 and fittingagainst the side walls l of the chimney and spacing the side platestlieretrmn. rlhe side plates are maintained in such spaced relation byan inclined bacl; plate la, extending upwardly and forwardly at anintermediate point between the liront and rear walls ot' the chimney andhaving its side edges arranged in inclined grooves l5 in the inner facesof 15 the side plates l2. 'lhe grooves are stamped or formed in the sideplates l2, and when the parts are assembled, the side edges et the backplate are interlocled with the side plates, and the latter aremaintained in position at opposite sides ot the chimney. The

inclined back plate, which extends to a point above the horizontal planeof the top ot the lireplace opening, as illustrated in Fig. l of thedrawing, may be connected with the rear wall of the chimney by shortbraces lo,

with any suitable material, such as mortar,

lirebricl; and other non-combustible material. rllhe chimney is providedat the bottom with a. rectangular hearth plate 19, constructed ofsuitable metal and being of a le .size to cover the bottom ot thechimney and provided with side and rear grooves 20 and 2l to receive thelower edges of the side and back plates, as clearly shown in lilies. land l-"Ql the drawings.

The chimney is equipped at a point above the fireplace opening with anoblong damper Q2, provided. at itsl rear edge with a pintle rod which ismounted in suitable bearing openings 2l in the upper portions of theside plates adjacent to 'the rear edges thereof.

The inclined rear plate extends to the upper edges et the side plates,and the damper is hinged at a point below the plane of the upper ec ofthe inclined plate, and it is 05 adapted when closed to rest upon theupper edge of the said inclined plate in an inclined position, asclearly illustrated in Fig. l of the drawing. rllhe damper entendssubstantially from the rear wall ot' the chimney to G0 the blower, thedamper being spaced at the l'ront and rear from the said rear wall andthe blower' or screen a distance equal to the thickness oli a piece ofsheet metal so as to clear the said rear wall and blower or screen. Thepintle is provided at one end with a short arm 2li, arranged to operatein the adjacent side space l? and connected to the rear end of anoperating rod The arin is provided with an eye, which is linked into a.similar eye of the operating rod, and the latter, which pierces thefront wall of the chimney, is equipped at its outer or liront end with asuitable handle 2G to enable it to be readily grasped. The rod isadapted to slide inwardly and outwardly to swing the damper upwardly anddownwardly.

rllhe fireplace of the chimney may be equipped with a grate o-r heateror any other suitable means :t'or supporting and burning the fuel. lll edamper is adapted to be closed to keep the heat in the room after thesmoke has escaped from the liuel and also after a lire has died out toprevent cold air from coming down the chimney and entering the room.rlhis result may also be accomplished by closing the blower or screen.The blower or screen also adapted to be closed when it is desired toerl'ectually prevent the lire troni dropping into a room or troni beingblown into the same by the down draft through the chimney, and it willrender a house perfectly salie night and also at other times when thereis no one present to attend to the lire. lllhen the blower or screen isopened a short distance, say three or Afour inches, it is adapted tocreate a stron g draft or suction through the Fireplace for causing arapid burning et the fuel. Also in seasons oi the year when a fire isnot needed, the blower or screen may be closed to conceal the fireplace.The front of the chimney may be linishcd in any suitable manner and thescreen may be ornamented so as to present an attracthie appearance. Alsothe improvements may be applied to ordinary chimneys constructed ofbrick, stone or analogous material.

lllhat is claimed is :u

l. rlhe combination of a chimney including trent, rear and side wallsand provided atthe front wall with a lireplace opening, a. blowermounted at the said lireplace opening and slidable downwardly andupwardly to cover and uncover the saine, a rear inner plate extendingupwardly from the bottom ot the chimney and spaced from the rear wallthereof, and an inclined damper pivA otally mounted in the space betweenthe inner r rar plate and the rear wall of the chimney at a pointslightly below the upper edge ot' the said rear plate and extendingforwardly over the sa and resting thereon with its front edge arrangedin close proximity to the said blower.

'l he combination ot a chimney includ ing lront, rear and side walls andprovided at the 'liront with a i'ireplace opening, inner upright ideplates extending from the trent of the chimney to the rear wall thereofand arranged in spaced relation with the side CII walls to form sidespaces, an inner rear plate extending upwardly from the bottom of thechimney in spaced relation with the rear wall thereof to provide a rearspace and connected at its side edges to the said inner side plates, ablower mounted at the replaoe opening and slidable downwardly andupwardly to Cover and uncover the saine, a damper pivotally mountedbetween the side plates in the space between the rear plate and the rearwall of the Chimney and at a point below the upper edge of the said rearplate and extending forwardly over the same and resting thereon andhaving its front edge arranged in close proximity to the blower, andoperating means connected with the damper and arranged in one of thesaid side spaces.
